Is survival bonus bugged or removed?

I’m trying to complete all achievements, and yesterday I focused on Survivor and Savior.
Took me a while to finish Savior, I had no messages displayed about the bonus, but I could see the achievement counter incrementing.
But Survivor… I couldn’t make survival bonus trigger once, no messages, no counter incrementing. I even created a new character to make it easy to get to less than 5% life, and one time I had literally 1 hp, and I healed right after, still nothing.
So, is it working?
